求翻译：传统的含油废水的处理方法虽然较多，但各种方法都有其局限性，用单一的方法来处理往往达不到排放要求。因此，在实际应用中，通常将几种方法组合起来，形成多级处理工艺，使出水水质达到排放标准。针对这种状况，在积极寻求新的处理机理的同时，开展利用几种处理方法联合作用的油田采出水处理新技术的研发，是解决当前采出水处理中存在的不足的一种可行途径。可见，开展好油田采出水处理方法的研究，将有效地缓解石油行业污水外排和清水消耗的矛盾。是什么意思？

Although traditional oiliness waste water processing method many, but each method all has its limitation, processes with the sole method often cannot meet the emissions requirements.Therefore, in the practical application, usually combines several methods, forms the multistage processing craft, enab

Although more traditional oil-containing wastewater treatment methods, but the method has its limitations, using a single method to process often does not meet emissions requirements. Therefore, in practice, it is common to combine several methods, form a multi-stage treatment process, to achieve em
